Justin Timberlake was said to have been fixated with his girlfriend Jessica Biel backstage after a recent show, despite being surrounded by a brood of glamorous models.

The singer, who presented the major fashion William Rast show at the Mercedes-Benz Star Lounge, was reportedly a one-woman man maintaining his distance from the other stunning members of the opposite sex.

"There were all these models like Erin Wasson, Coco Rocha and May Andersen vying for his attention," the New York Daily News quoted an eyewitness as saying.

"But Justin only had eyes for Jessica," the witness added.

The couple were later spotted picking up matching pairs of Havaianas flip-flops on their way to the show's after-party at Rose Bar.

An eyewitness added: "They were all over each other and PDA-ing like crazy!"
